Echinacea + Propolis El Naturalista is a food supplement in vials that combines the properties of Echinacea with the benefits of Propolis. Both compounds are traditionally used to stimulate the body's defenses. Echinacea is a plant that helps improve the functioning of the immune system by strengthening defenses. Propolis is a substance that bees obtain by processing tree resins in their salivary glands, thus converting it into a natural antibiotic that they use to protect the walls of the hive. Propolis is a substance composed of resin (50%), wax (30%), essential oils (10%), pollen (5%), and other organic compounds, including flavonoids (galangin, quercetin, etc.). These phenolic compounds are responsible in most cases for its properties. Honey is a highly nutritious food rich in vitamins, trace elements, and carbohydrates that strengthens the immune system and provides energy. Format: 20 Units.
